Abstract (en)

[origin: WO2007128008A1] The invention relates to a cooling system (13) for a fuel cell (1) having at least one cooler (14), a thermostat (18), a pump (15) for delivering a coolant (17) in a cooling cycle (16), and having an equalization container (20), wherein a deionizing resin (19), which is arranged in the equalization container (20), is provided for reducing the electrical conductivity of the coolant (17), and wherein the equalization container (20) is connected to the cooling cycle (16) via at least one line (21). In order to provide such a cooling system (13), in which the electrical conductivity of the coolant (17) can be kept continuously low in a simple and cost-effective manner, provision is made for the deionizing resin (19) to be arranged in a container (22) in an interior (24) of the equalization container (20) such that the deionizing resin (19) enters at least partially into the coolant (17) and the line (21), which connects the equalization container (20) and the cooling cycle (16), is freely accessible.
